SCREEN-SHOE FOR CLOVER-HULLERS.

SPECIFICATION forming part of Letters Patent No. 500,136, dated June 2'7, 1893.

Application filed January 23, 1893. Serial No. 459.422- (No model.)

To all whom it may concern:

Be it known that I, JOHN N. KAILOR,a citizen of the United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented a new and useful Improvement in Screen-Shoe for Clover-Hull ers, of which the following is a specification.

My invention relates to an improvement in the vibrating-shoe which carries the separat- Io ing-screens in a clover-hulling machine.

The object of my improvement is, to save and to direct into thetailings-troughs, seeds ivhich have heretofore been blown out and The accompanying drawings illustrate my invention.

Figure 1 represents a vertical longitudinal section of the lower part of a clover-hulling 7 machine havingmy improvement. Fig.2 rep- 2o rlelsents aplan of the rear portion of the screen- In the drawings, A, indicates the blast-fan of the clover-huller; B the tailings-troughs; O the conveyer mounted therein, and D the end- 2 5 less-belt carrier on which the stems and refuse are discharged. The vibrating screen-shoe, E, is hung in the body of the machine in the path of the blast from the fan A, in the usual well known manner.

0 The current of air from the blast-fan, after passing the screens, is intercepted and deflected to accommodate the condition of the stock, by means of the adjustable blast-board, F. Heretofore, seeds passing the blast-board F have been thrown out onto the carrier with the chaff, and have been lost. For the purpose of saving these seeds, I extend the sides of the shoe rearward beyond the blast-board a sufficient distance to receive between the extended sides the inclined end-board, G,

which is mounted, preferably, between cleats,

H, and I, secured to the inner sides of the extended ends of the screen-shoe, so as to be withdrawn when occasion requires. The

5 lower edge of the end-board G rests upon a shelf, J, secured in the body of the machine at the rear of the tailings-trough and communicatin g therewith at the front edge of the shelf, so that, as the shoe vibrates longitudinally, the lower edge of board G slides back and forth upon the shelf .I and scrapes whatever may have accumulated thereon into the failings-trough.

For the purpose of conveying the stems which pass from the uppermost screen in the screen-shoe over the extended portion of the shoe, I provide a removable open grating, K, which rests upon the upper edges of the extended portion. of the shoe.

In operation, the blast of air passing from the screens of the screen-shoe, and carrying such of the seeds as have failed to pass through the screens, is deflected upward by the adjustable blast-board, F, thus forming a partial vacuum or eddy at the rear of the blast-board, into which the seeds fall, and, falling upon the inclined end-board G, slide downward to the shelf J, and are, by the vibratory action of the shoe and the scraping movement of the end-board upon the shelf, delivered into the tailings-trough, from which they are carried, with the unthrashed clover-heads, by the conveyer O to the tailings-elevator, (not shown) in the usual manner.

I claim as my invention- 7 5 In a'clover-huller having a blast-fan, a tailings-trough, and a blast-board arranged above and at the rear of the tailings-trough so as to deflect the current of air from the blastfan, the combination with said fan, tailings- 8o trough and blast-board, of the shelf arranged at the rear of and communicating with the railings-trough, the vibrating screen-shoe arranged in the path of the blast from the fan and having its sides extended beyond and at the rear of the blast-board, and the inclined end-board mounted between the extended sides of the screen-shoe and resting upon said shelf, whereby the seeds passing the blastboard are caught upon the end-board and delivered to the tailings-trough, substantially as set forth.

JOHN N. KAILOR.
